Ralik Hansen, 28, was one of at least five thieves who raced inside the crowded Midtown store through a side entrance at 12:30 p.m. Jan. 31, cops said.

More than a dozen shocked customers and staffers watched as the crooks used hammers to smash a display case and scoop out 16 timepieces worth $709,000, sources said.

The robbers then bolted with the jewelry.

The FBI, assisted by the NYPD, have tracked down four of the perpetrators and charged them with robbery in connection with a series of high-end jewel heists in New York, New Jersey and Virginia.

The 6-foot-1, 205-pound Hansen was last seen with a shaved head and noticeable scars on his left wrist and left elbow. He frequents several haunts in Brooklyn and is commonly referred to “Rahlik” or “Rah.” He has family in Georgia and the country of Panama.

Hansen, who is believed to be armed and dangerous, has been charged and indicted in the Cartier case. He is also wanted for at least two other robberies in New Jersey and Virginia.
